swift - dataTask 错误 - "Cannot invoke ' dataTask'，其参数列表类型为...”

Question

我遇到了一些麻烦。查看下面的这部分代码:

// Create a datatask and pass in the request
            let dataTask = session.dataTask(with: request, completionHandler: { (data:NSData?, response:URLResponse?, error:Error?) in

                // Get a reference to the image view element of the cell
                let imageView = cell.viewWithTag(1) as! UIImageView

                // Create an image onject from the data and assign it into the ImageView
                imageView.image = UIImage(data: data!)

            })

我在第二行收到错误，这是错误:

我该如何解决这个问题？提前致谢!

根据一些评论，我有了答案!我将“请求”从 NSURLRequest 更改为 URLRequest，并将代码更新为:

  // Create a datatask and pass in the request
            let dataTask = session.dataTask(with: request, completionHandler: { (data, response, error) in

                // Get a reference to the image view element of the cell
                let imageView = cell.viewWithTag(1) as! UIImageView

                // Create an image onject from the data and assign it into the ImageView
                imageView.image = UIImage(data: data!)

            })
